Intervertebral-preparation tool

Abstract

An intervertebral preparation tool, i.e. a material-removing tool for intervertebral preparation, includes a cutting head (2) which includes at least one movable blade (8) which is held by at least three pivotable levers. The levers (14, 16, 18) are each configured in a rigid manner. A first (14) and a second (16) lever are each articulated at a first articulation point (20) on the blade (8) and at a distanced second articulation point (22) on a carrier element (10) of the cutting head (2), a third lever (18) is articulated at a first articulation point (20) on the blade (8) and at a distanced second articulation point (24) on an actuation rod (26) which is displaceable relative to the carrier element (10). The articulation points (20, 22, 24) are configured as pivot joints with pivot axes which are parallel to one another.
